Application led December v31, 1921,7`Serial No. 526,199. Renewed March 28, 1924.

Tov all whom 'it 'may concer/n:

Be it known that we, ELMER O. BEARDS- LEY and WALTER F. PIPER, bo'th citizens of the'United States, and residents of Chicago,

`v in the county of Cook and State oflllinois,

have invented certain new and useful Improvements in Machines for Making Molds,

of which the following isa full, clear, and

exact description. 1o v making molds andmore particularly to those embodying a high-speed projector for rapi idly filling and packing sand into flasks con* ltaining patterns.

The primary object ofthe invention is to 'provide means -for delivering lia'sks to and from ai projector -with facility so that the idle periods of the (projector willie reduced to a minimuman the outpntfwill vbe in'- creased. Other objects willwappear from the description ofthe machine? i The invention consists inthe' several novel features hereinafter set forthand more particularly 'defined by claiinsat the 'conclusion --"'"In',the' drawings :l Fig. 1 is -a side elevation of ya machine embodying the invention.' 'F ig. 2is aI vieni-showing' the driving mechanism atl onefside.oflthefinachine I Fig. .3 is a plan.` l so Fig.' 4. is a section on line 4 4.of -F1g."3. Ap

' Fig. 5,;is "a'detail of the brake for the turn- Fig.. 6 is a front elevation. Fig. 7 isa detail of the-projector.

t `The invention is exemplified infa machine comprising a portabrlx' carriage equipped with a projector and echanism for' feeding sand from a pile on [the ii'or to the projector and, a turntablemovable with the carriage Tand adapted to deliver the as'ks'toand from a point where they may hgpeadily filled by the projector..`4

The carriage comprises sides 11,'. tubular 'crossmembers 12, 13 which are hrigidly se-l ic'ued to the sides by -U-bolt clamps 14, 45 ltoothedftractionwvheels 15, ada ted to run on ltracks A16 in the foundryoor-` and to mesh with racks 1'( on the tracks, and wheels- 18.. vThe carriage; is propelled 'to advance the machine over'and into a pile of `sand on ,lill the floorhy an electric. motor'19 secured to abracket 20 which Q xi'ed tothe carriage,

the toothed traction wheels 15. The invention .relates to 'machines for' Vrotor-shaftextending through arm 34;

a -pinion 21 on the shaft of said motor, a gear 22 driven by said pinion,'a pinion 23 integral with gear 22, a gear 24, a crossshaf't 25 fixed to g'ear 24, a Wrist-pin 26 fixed to one end of shaft 25, a pawl 27 operated by s aid wrist-pin and adapted to stop up a ratchet-wheel 27, and a pinion 28 integral with the ratchet and meshing with one of The latter are cross-connected `so they will be synchronously driven by a cross-shaft 29 which extends through the tubular frame-member 13. The projector comprises a casing or stator 30, a rotor 31 provided with a blade 32or 65 projecting wads, of -sand at high-speed into the flasks B3; a tubular arm 34 on the outer end of 'which the projector is sustained; a

an electric motor 36 mounted on the inner end of said armA and geared to drive shaft 35; and a jib 368L to the outer end of which arm 34 is pivoted and having its inner end ivotally sustained by a standard 37 which' 1s4 suitably secured to the tubular members 75 12'and 13 of -the carriage. This post is disposed at one side of the carriage so that the projector may b'e moved over a flaskl disposed centrally over the carriage and laterally of the post, the -jib and arm being so rovided to permit tlie projector to bemoved laterally to fill yall portions of a {iask without varying the angle of delivery ofthe sand.- Y' z Themechanism for feeding sand to theA 85 projector from a pile of prepared sand on the foundry-door and between the tracks 16 comprises a helical conveyor 38 which is fixed to and driven from motor 19 b shaft 25, and is providedwith blades 39 or dis- 9o integrating the sand and adapted tov feed the sand crosswise of the carriage to a point adjacent to one side of the carriage, an ele. vator having a series of buckets 40a on an endless chan40, asproclret 41 fixed to shaft 95 25 so it will be driven from motor 19 and i the gearing heretofore described, and so it 'will drive the elevator, an. idler sprocket 42 for the upper end ofthe chain 40'and a shaft 43 for'said idler sprocket, which is 100 mounted in levers 44-which are pivoted'to v standards 45 and are pressed andheldin belt 48 w position to keep the chain taut by a springconnectiou 46. The screw-conveyor 38 with its blades 39 feeds the sand crosswisc from the pile on the -floorto theelevatonbuckets 6 40? which discharge the sand into a guide jlb, and helt 48 is sustained on ai'in 34 and driven from .motor 3G, as more fully shown in Patent No; 1,408,493, granted to us May 7, 199:2, to which refcreneemay be had for a detail description thereof.. The belt 48 feeds the sifted sandV to the projector in regular quantity so the projector lade will forciblyisling wads of sand into the flasks.

llfechanism adapted to deliver flasks to and from the projector is mounted to triivel with the. projector carriage and comprises a turntable 5() on which la series of plates 5l'. each adapted to support a flask 33,'ar`e sel cured. The turntable is provided with a hub' 52 which is journalled in a hearing 58 which is secured by'ibolts 54 toa truck which is connected to the projector carriage. 'This truck comprises a frame composed of sills and an axle' 56 which carries a roller 5T and -secures the sills together. The `trontends of the sills 55 are` each pivoted to a pin 58 .which is carried in a block 59 which is Seoured'by a U-clanip G0 to the tubular member' 13 of the projector carriage.. This truck rotatably supports the turntable for 4o the flasks so it will be advanced with the projector carriage and projector. The plates 5l are arranged so they will successively pass into position to bring the flasks thereon beneath the Apro] removed therefrom and re-loaded, while the pro'ector is filling a flask. that is to say, wlii e one flask is being filled with sand, *other flasks may be placed on some of the plates 51 in readiness to he successively vonveyed into operative relation and be filleil by the projector, so that filled flasks may be simultaneously removed from some ot' the other plates 5l. As a result, the idle periods A of the projector are reduced to a iiiiuiiiium.

'Each plate 51 is' provided with pins (lil to slip into the usual lugs on the flasks.

A brake is provided to secure the turntable. in its assigned positions to successively hold o0 the flasks. under the projector. This. brake comprises a brake-hand 62 adapted to gripw colufnm-in lieu of a column on a, portable a friction drum 63 on the turntable and ha vmg one of its endssecured. as at G4. to one of the sills 55 and its other end connected,

ector 30 and to bring them into 45 position so the flasks may be conveniently said sill at 67. VStuds 68,' carried by the turn-A table 50, are adapted to engage the lever 66 to hohl it in position to retain the brake-- band 62 in operative position.l Theouter end of lever (3G is provided-with a foot-piece 69. As the flasks are successivel filled by the projector, the operator wi l depress treadle. G9 sufficiently to cleari'ts c'oactiner stud 68. The turntable will then be released so it can be rotated to bring an empty flask on one of the plates 51 into position to filled.

follows: lVhile the projector-carriage is be,- ing propelledforwardly, the cross-conveyor 3S and elevator 40, 40 will deliver sand into` The operation of the machine will beA f the chute 47, in which it willbe sittedi.v The u onto the feed-belt 48 carried by the arm 34 and which will supply sand tofthe )rojector 30, 31 in regulated quantity. Fl sks with patterns therein will' he placed ou the plates 5l at one side of the plate disposed beneath the projector, and the turntable will then be rotated one step to bringfan empty flask into operative range .of the projector. The

operator in charge of the projector will` I uanipulate it over said flask until it has one step. Simultaneously, other workmen' will litt the filled flasks from the plates l51 which have passed away from the projector. j

During.eaclishifting operation of the turntable, one of the operators will" first vrelease' lever (i6, rotatethe turntable one step and then set the lever to apply the brake-band 62 so'the. turntable will be secured against rotation.

The invention exemplifies a'moi'ilding machine in which provision is made for speedily and successively bringing empty flasks into 'sifted sand from chute 47 will be discharged position to be filled by .the projector and to i be removed so that the idle periods of the projector will be reduced to a minimum. By facilitating the. delivery' of theflasks to the projector and their lremoval When filled, the

output,Y of the projector is materially linvv vcreased over methods heretofore employed, in which the projector necessarily remained idle while the flasks were being manually brought to and removed from the projector.

'lhc invention is exemplified in connection with a portable moulding: machine. although 'it is to be iuiderstood that certain features thereofare. applirable to a projector in which the supportingr jih is pivoted to a stationary carriage. j liilc the invention has been illustrated in 65 asatjli, to a'lever 66 which is pivoted to connection with a projector, it is to be understood that certain features of the invention may be used with other means for delivering sand from the elevator tothe flasks on the turntable and that the claims arenot to be understood as restricted to combinations including a projector, except where the same is specified.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention. j
